For example, the antibodies described herein are capable of binding to ErbB3 and inhibiting EGF-like ligand mediated phosphorylation of the receptor. A first pair of the weight sensing devices supports one of the pair of mounting plates and a second pair of the weight sensing devices supports the other of the pair of mounting plates. The row addressing signals have, in a first period, at least one voltage value serving to break the anchoring of all of the pixels in the row.
